Referring to FIG. 1, there is shown a block diagram illustrating thefunction of a separate computing system according to the firstembodiment of the present invention. As shown in FIG. 1, there is aseparate computing system 100 of the present invention, comprising: aprimary computing device 1 comprising a display unit 11, a computingunit 12, a memory unit 13, a signal receiving unit 14, and a powersupply unit 15; and a sensing device 2 comprising a signal transmissionunit 21, a sensing unit 22, and a power supply unit 23.

The sensing unit 22 of the sensing device 2 is capable of detecting auser's physiological information such as, for example, informationrelating to one or more of the user's blood pressure, pulse, voice,vibration, and temperature. The signal transmission unit 21 of thesensing device 2 receives a message from the sensing unit 22 andtransmits externally the message via wireless communication. Preferably,the signal transmission unit 21 is selected from one of a WiFicommunication unit, an NFC communication unit, a RFID communicationunit, a Bluetooth communication unit, a Zigbee communication unit, andan infrared communication unit. The power supply unit 23 of the sensingdevice 2, which can be, for example, one of a lead-acid battery, anickel-cadmium battery, a nickel-hydride battery and a lithium ionbattery, is configured to supply power to all electronic components inthe sensing device 2.

The signal receiving unit 14 of the primary computing device 1 receivesinformation transmitted by the signal transmission unit 21 of thesensing device 2. Preferably, the signal receiving unit 14 is selectedfrom one of a WiFi communication unit, an NFC communication unit, a RFIDcommunication unit, a Bluetooth communication unit, a Zigbeecommunication unit, and an infrared communication unit. The computingunit 12 of the primary computing device 1 performs the processing orcomputing operation on the information received by the signal receivingunit 14, stores a result of the processing or computing operation in thememory unit 13 and/or displays the result of the processing or computingoperation on the display unit 11. The computing unit 12 refers generallyto a logical computing device capable of executing complex computerprograms, such as an integrated circuit central processing unit or amicroprocessor. The computing unit 12 can have one or more cores and ispreferably capable of parallel computing or synchronous multithreadedcomputing. The memory unit 13 includes a volatile memory and/or anonvolatile memory and is configured to store the data of the primarycomputing device 1. The power supply unit 15, which can be, for example,one of a lead-acid battery, a nickel-cadmium battery, a nickel-hydridebattery and a lithium ion battery, is configured to supply power to allelectronic components in the primary computing device 1. Moreover, thedisplay unit 11 of the primary computing device 1 is selected from oneof a screen, a projection device, an audio device, and at least one LEDlamp.

Referring to FIG. 2, there is shown a flow chart illustrating theoperation of the separate computing system according to the firstembodiment of the present invention. As shown in FIG. 2, steps S21˜S22are implemented on the sensing device 2, and steps S23˜S25 areimplemented on the primary computing device 1. For the sake of betterunderstanding of the present invention, the primary computing device 1is exemplified by a smartphone, and the sensing device 2 is exemplifiedby a wristband capable of sensing physiological information. Thephysiological information is preferably the blood pressure-relatedinformation or pulse-related information. However, a person havingordinary knowledge in the art understands that the primary computingdevice 1 can be one of other mobile communication devices, such as atablet computer, a notebook computer, a hand-held game console, and amultimedia player, and that the sensing device 2 can be a contact lenswith sensing capability or a heart stent with sensing capability,without departing from the spirit and scope of the present invention.The first embodiment described herein is to be deemed as illustrative,rather than restrictive, of the scope of the present invention.

In step S21, the sensing unit 22 of the sensing device 2 senses theuser's physiological information such as, for example, one of the bloodpressure-related information, the pulse-related information, theestimated step count-related information, and the bodytemperature-related information, but not limited thereto. In step S22,the signal transmission unit 21 of the sensing device 2 transmitsexternally the physiological information having not yet undergone thecomputing and processing operations. The phrase “having not yetundergone the computing and processing operations” refers to thecondition that the value detected by the sensing unit 22 is directlytransmitted externally via wireless transmission without specialencoding or encrypted computation. Thus, the sensing device 2 does notrequire any high-performance computing unit. Moreover, in practice, itis feasible to set a transmission condition for the sensing device 2,for example, under which wireless signals are regularly transmitted tothe primary computing device 1 via the signal transmission unit 21, orwireless signals are transmitted externally via the signal transmissionunit 21 when the sensing unit 22 senses that the subject's physiologicalinformation exceeds a critical value.

Referring to step S23, the signal receiving unit 14 of the primarycomputing device 1 receives the physiological information. As shown instep S24, the physiological information is then transmitted to thecomputing unit 12 to undergo the computing operation whose result can,for example, be used to determine whether the blood pressure-relatedinformation is within a normal range, determine whether thepulse-related information is within a normal range, calculate thecalories burned or the distance walked according to the estimated stepcount-related information, and determine whether the bodytemperature-related information is within a normal range, but is notlimited thereto. In step S25, the primary computing device 1 informs auser 5, via the display unit 11, of a result of the processing orcomputing operation which indicates whether, for example, various datarelating to the user's blood pressure, pulse, calories, and bodytemperature are within their respective normal ranges, hence the user 5can obtain the physiological information in a real-time manner and knowswhether or not the physiological information is within a normal range.It is to be noted that the user 5 watching the display unit 11 and thesubject being measured by the sensing device 2 can be the same person ordifferent persons, and thus the separate computing system of the presentinvention is widely applicable to the measurement made by thephysician/patient or oneself.

As can be seen from the above embodiment, certain physiologicalinformation, after being obtained by the sensing device 2, istransmitted, via wireless transmission, to the primary computing device1 to undergo the computing and processing operations performed by thecomputing unit 11 of the primary computing device 1, and then the resultof the computing and processing operations is displayed on a screen(i.e., the display unit 11) of the primary computing device 1. With sucharrangement, the sensing device 2 is exempted from complicatedprocessing or computing operations, and thus the number of essentialcomponents thereof can be minimized (for example, no high-performanceprocessor or memory is required), thereby fulfilling the goals ofminimized weight and low power consumption. In other words, the presentinvention is advantageous in that the sensing device 2, instead of beingequipped with components of high power consumption and great weight,such as a processor, a memory and a display unit, exploits a centralprocessing unit of a smartphone (i.e., the primary computing device 1)to perform the computing operation, and that the result of the computingoperation is presented to the user 5 on the screen (i.e., the displayunit 11) of the smartphone, thereby reducing the weight and powerconsumption.

Moreover, as the sensing device 2 of the present invention ischaracterized by minimized weight and low power consumption, it isapplicable not only to the aforesaid wristband but also to a heart stentwith sensing capability that detects a width of a cardiac blood vesselof a user with a sensing unit 22 thereof. Alternatively, the sensingdevice 2 is applicable to a contact lens with sensing capability thatdetects the blood pressure at the user's ocular capillaries with asensing unit 22 thereof.

Referring to FIG. 3, there is shown a block diagram illustrating thefunction of a separate computing system according to the secondembodiment of the present invention. FIG. 3 is different from FIG. 1 inthat the sensing device 2 has a first wireless communication unit 24 forreceiving and transmitting wireless signals, and that the primarycomputing device 1 has a second wireless communication unit 16 forreceiving and transmitting wireless signals. In the second embodiment,the primary computing device 1 and the sensing device 2 communicate witheach other by one of WiFi communication, NFC communication, RFIDcommunication, Bluetooth communication, Zigbee communication, andinfrared communication. In other words, unlike the signal transmissionunit 21 and the signal receiving unit 14 of the first embodiment, thefirst wireless communication unit 24 and the second wirelesscommunication unit 16 of the second embodiment are capable of two-way(receiving-and-transmitting) wireless communication. Moreover, in thesecond embodiment, the primary computing device 1 further has a controlinterface unit 17. The control interface unit 17 provides aphysiological information reading interface for making available thecorresponding information according to the user's click selection. Forinstance, the user can make enquiries, via the physiological informationreading interface, as to the fluctuations in body temperature over thepast week or the average pulse over the past hour.

Referring to FIG. 4, there is shown a flow chart illustrating theoperation of the separate computing system according to the secondembodiment of the present invention. As shown in FIG. 4, steps S41˜S42are implemented on the primary computing device 1, and steps S43˜S44 areimplemented on the sensing device 2. For the sake of betterunderstanding of the present invention, the primary computing device 1and the sensing device 2, like those disclosed in the first embodiment,are exemplified by a smartphone and a wristband capable of sensingphysiological information, respectively. Similarly, the secondembodiment is illustrative, rather than restrictive, of the scope of thepresent invention. The flow chart in FIG. 4 omits similar operationprocesses depicted in FIG. 2, such as the regular transmission ofphysiological information relating to the sensed blood pressure, pulse,calories, body temperature, etc., to the primary computing device 1 bythe sensing device 2.

Referring to step S41, the user enters a sensing device settinginstruction via a touchscreen or a physical key (i.e., the controlinterface unit) of the smartphone (i.e., the primary computing device1). For instance, the user clicks on the touchscreen to set the currentphysiological information to be detected as the pulse-relatedinformation and set the detection interval to be 10 minutes. In stepS42, the smartphone transmits, via the second wireless communicationunit 16, an uncoded wireless setting signal based on the sensing devicesetting instruction, and the wireless setting signal contains thesensing device setting instruction which has just been entered by theuser.

In step S43, the first wireless communication unit 24 of the sensingdevice 2 (i.e., the wristband) receives the wireless setting signal. Instep S44, the sensing device changes the value of a register thereofaccording to the wireless setting signal such that it detects asubject's pulse once every 10 minutes. Hence, the primary computingdevice 1 can not only display the data sensed by the sensing device 2but also allow the user to directly and conveniently manipulate themeasurement settings of the sensing device 2.

Referring to FIG. 5, there is shown a block diagram illustrating thefunction of a separate computing system according to the thirdembodiment of the present invention. The embodiment illustrated in FIG.5 is different from the embodiments illustrated in FIGS. 1 and 3 in thatthe primary computing device 1 is capable of synchronously controllingmultiple sensing devices (exemplified by a first sensing device 3 and asecond sensing device 4) via the second wireless communication unit 16,and that the primary computing device 1 further comprises an identityauthentication unit 18 configured to perform an identity authenticationprocedure on the first sensing device 3 and the second sensing device 4.In practice, the identity authentication unit 18 performs the identityauthentication procedure according to the hardware IDs or media accesscontrol addresses (also known as MAC addresses) of the first sensingdevice 3 and the second sensing device 4.

Referring to FIG. 6, there is shown a flow chart illustrating theoperation of the separate computing system according to the thirdembodiment of the present invention. As shown in FIG. 6, steps S61 andS62 are implemented on the first sensing device 3, steps S63 and S64 areimplemented on the second sensing device 4, and steps S65˜S67 areimplemented on the primary computing device 1. For the sake of betterunderstand of the present invention, the primary computing device 1 isexemplified by a smartphone, the first sensing device 3 is exemplifiedby a heart stent with sensing capability, and the second sensing device4 is exemplified by a contact lens with sensing capability. Similarly,the third embodiment is illustrative, rather than restrictive, of thescope of the present invention.

Referring to step S61, a heart stent (i.e., the first sensing device 3)undergoes the identity authentication procedure performed by thesmartphone (i.e., the primary computing device 1) via, a first sensingcommunication unit 31. In step

S63, the contact lens (i.e., the second sensing device 4) undergoes theidentity authentication procedure performed by the smartphone via asecond sensing communication unit 41. In step S65, the wirelessauthentication signals from the heart stent and the contact lens, afterbeing received by the smartphone, are delivered to the identityauthentication unit 18 that performs the identity authenticationprocedure on the sensing devices. In steps S62 and S64, the heart stentstarts to sense the user's physiological information (e.g. a width of acardiac blood vessel), and the contact lens also starts to sense theuser's physiological information (e.g. the blood pressure at ocularcapillaries) after successful identity authentication, and then thesensed physiological information is transmitted to the smartphone.Moreover, it is preferable that the heart stent and/or the contact lensare/is configured to transmit, via, the first sensing communication unit31 or the second sensing communication unit 41, wireless signals to thesmartphone only when the sensed physiological information exceeds acritical value (for example, when the blood pressure exceeds 140 mmHg)so as to reduce the power consumption.

Referring to steps S66˜S67, the second wireless communication unit 16 ofthe smartphone receives and transmits the physiological information tothe computing unit 12 to undergo the computing operation, and informsthe user of a result of the computing operation via a screen (i.e., thedisplay unit 11). Hence, the user knows the width of a cardiac bloodvessel and blood pressure in a real-time manner. In other words, theuser can instantly obtain information measured by multiple sensingdevices.

Moreover, according to the conception of the present invention, anotherapplication involves the combination of a sensing device and a warningdevice. The sensing device comprises a power supply unit, a sensingunit, and a first wireless communication unit. The power supply unit isconfigured to electrically connect and supply power to the sensing unitand the first wireless communication unit. The sensing unit isconfigured to sense the user's physiological information and to transmitexternally a warning message via the first wireless communication unitwhen the sensed physiological information exceeds a standard value. Awarning device comprises a warning unit and a second wirelesscommunication unit. After the second wireless communication unit hasreceived the warning message, the warning unit performs a warningoperation.

For instance, the sensing device is an electronic sphygmomanometerequipped with a short-range wireless communication unit and embedded ina garment. The sensing device transmits, via the short-range wirelesscommunication unit, a

warning message to a microcomputer (i.e., the warning device) regularlyor when the sensed physiological information exceeds a standard value(for example, when the sensed blood pressure exceeds 140 mmHg). Themicrocomputer has a buzzer (i.e., the warning unit) and a secondwireless communication unit. After the second wireless communicationunit has received the warning message, the buzzer starts to sound towarn the user.

Preferably, the warning device further comprises a computing unit (e.g.a microprocessor) configured to perform the computing operation on thephysiological information contained in the warning message, and performsvarious respective warning operations according to the result of thecomputing operation. For example, slow sounds are generated when theblood pressure falls within the range of 140-160 mmHg, and shortinterval sounds are generated when the blood pressure exceeds 160 mmHg.It is preferable that the warning device is a pocket-sized computer or amicrocomputer, and that the warning unit is selected from one of anaudio device, a display device, and a vibration device.

In conclusion, a separate computing system of the present inventionenables complex calculation operations and display to be performed on asmartphone via wireless transmission, and thus a sensing device, such asa wristband, a contact lens, or a heart stent, requires either noprocessor at all or only a simple microprocessor for facilitating thedisplay of content. Therefore, the sensing device not only haselectronic sensing capability but also fulfills the goals of minimizedweight and low power consumption.

The preferred embodiments described above are exemplary and are notintended to limit the scope of the present invention.
